[edit] CleanModules

Clean up all kernel modules that can be removed.

Usage: CleanModules

Options:

• -h, --help - Shows this help.
• -v, --version - Show program version.
• -V, --verbose - Enable verbose mode.

This script attempts to perform "rmmod" on all modules, repeating the process as the module dependency relations are cleared, until no more modules can be removed (ie, if there are no more loaded modules or all loaded modules are in use).
